Chapter 4, Problem 42AP

A pendulum with a cord of length r = 1.00 m swings in a vertical plane (Fig. P4.42). When the pendulum is in the two horizontal positions θ = 90.0° and θ = 270°, its speed is 5.00 m/s. Find the magnitude of (a) the radial acceleration and (b) the tangential acceleration for these positions. (c) Draw vector diagrams to determine the direction of the total acceleration for these two positions. (d) Calculate the magnitude and direction of the total acceleration at these two positions.

An ice skater is executing a figure-eight, consisting of two identically shaped, tangent circular paths. Throughout the first loop, she increases her speed uniformly, and during the second loop she moves at a constant speed. When the ice skater travels during the first loop, the acceleration vector is not directed towards the center, whereas when the ice skater travels in the second loop, the acceleration vector is directed toward the center. Is this true or false?
A cannon is fired from the ground level, in a flat terrain, making an angle of 30° upwards with the horizontal. A bullet exits the barrel with a scalar speed of 980 m/s. If resistance can be neglected, what is the horizontal distance traveled by the bullet before it hits the ground? a) 43 km b) 4,3 km c) 8,5 km d) 85 km e) 170 km
A cannon ball is fired with an initial speed of 123 m/s at angle of 60 degrees from the horizontal. Express the initial velocity as a linear combination of its unit vector components.  ( m/s)  + ( m/s)  At the maximum height, the speed of the cannon ball is v =  m/s and the magnitude of its acceleration is a =  m/s2. The time needed to reach maximum height is t =  s. The maximum height reached by the cannon ball is H =  m.
